Depending on your implementation, it may be faster to re-derive the liberty list when you need it. For example, if your playout move suggester only suggests capturing the last stone played, you don't need to do all of the work to update liberty counts for any other chains. Thanks a lot

Hi Magnus. I think I have a properly up to date client now. Below is a sample configuration file I am using for gnugo. You can run it with the appropriate cgosGtp.something for your platform. I use cgosGtp.kit and use the tcl runtime for my platform but you can use one of the binaries.

I keep a count of the number of liberties for each string of stones. It's updated incrementally when each stone is placed. I only use it for finding captures. I don't read ladders during playouts. Keeping liberty counts is not expensive. I was getting 50k playouts per second on a 2.3 GHz

One is not so effective but simple. Trace all adjacent four intersections of all stones of a string with marking to avoid duplicate. The other is the combination of two dimensional shift, logical or, and logical and operations on bitboards using 128 bit (or wider) registers. -Hideki Łukasz
